JULlUS E. PITRAT, OF GALLIPOLIS, Ol 'llO PRICE-SCALE.

Application filed August ll. 1885. Serial No. 174,126.

To (015 whom it may concern.-

Be it known that l, JULIUS E. PITRAT, a

States, residing at Gallipolis, in the county of Gallia and State of Ohio, have invented certain new and useful Improvements in Couplings for Scales; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and ligures of reference marked thereon,whieh form a part of this specification.

This invention relates to certain new and useful improvements in scales, and has for its object to provide means whereby the pricescales described in my PatentNo. 314,717 may be attached to any ordinary platform-scales, so that the money value of a substance at any given price per pound placed on the platform of the scale can be ascertained without having recourse to arithmetical computation; and to this end and to such others as the invention may pertain it consists in the peculiar combination and novel construction and arrangement of the parts hereinafter more fully described, and pointed out in the claims.

In the accijimpauying drawings, which form a part of this specification, Figure l is a top plan view, and Fig. side elevation, of my improvement.

Referring to the drawings by letters, A rep resents a suitable base which may be of any desired form.

l is a carriage, preferred form.

which may also be of any This carriage is constructed to be moved back and forth on the base A, and is prcferal'ily mounted upon wheels (I, although it may slide in grooves, as shown, if desired.

O are standards or supports arising from the carriage ll, and in these standards is sup ported the lever D, which consists upon the right 0 power side of two twin branches, D D, and upon the left side of a single branch, D, extending from the pivot-bar d at a point midway between its connection with the branches D D", as plainly shown in Fig. 1. The branches D D of the lever are each provided with two sets of graduations, b 0, and

the branch D with two sets of graduations, g

l l l l l l 6, similar to those in my patent above referred to. The branch D is designed to be used as a balancing-beam, and receives the balanceweight E, while the branch D" is to receive the weighingbob F, as in said patent, while the carrier G is supported by the rod f connecting the ends of the branches D D". The branch D is simply used as a guide orlever for the weight E to slide on to counterbalance the scale when adjusted to the varying prices of merchandise, as will appea further on.

H is a standard fixed to the base A, and H is a coupler pivoted to said standard.

I is a link pivoted to the inner end of the coupler H, and its upper end is knife-edged, to engage the desired notch in the branch 1) of the lever. This link is kept in an upright position by means of a ballast-weight, i, said link and weight being made in one piece. Pivotally secu red to the opposite end of the coup ler H is the link 1', similar to the link I, and provided with a ballastweight, t.

J represents the beam of a plalforinscale, andj its weighing-bob.

K is a pivot-ed bale at the free end of the beam, and L is a rod, hooked at each end, connecting the bale K with the link 1 of the coupler. This rod is preferably, though not necessarily, provided with a carrier, M.

The operation is as follows: Suppose the article whose value is io be ascertained has just been weighed and still remains on the platform of the beam J. Move the scale car ried by the carriage B so that the link I will fall into the notch 0f the branch D, indicating the price per pound of the article being weighed. Then move the balancing-bob E along on the branch D to the right till the branch D" tips up and bears hard enough against the link I, to maintain it in place. Next move the bobj of the beam J to zero, and remove all the weights from the carrier M, when the beam will go up and press upward with a force equal to the down pressure exerted by said weights before being removed. The beam J being relieved of its counterbalancing-weight the load thereon will cause its free end to rise, and through the connections K, L, and 1" will cause the ascent of the left branch of the coupler H, which will cause a which, being connected to the branch D by the link I, will bear on the graduated beam with a force indicated in dollars and cents by the weighing-bob F when placed at the point of balance.

It will be noticed that the coupler H and the scale-beam J remain relatively fixed, whereas the carriage B and its scale are movable relative to the coupler and beam J. The position of this platform varies as the price per pound of the article weighed.

\Vhen the beam J is used for weighing purposes, the carrier M is necessary, but otherwise the hooked rod L without th e'carrier'will answer the purpose as well so far as computing money Value of an article placed on the platform is concerned.

I do not confine myself to the exact construction shown and described, but reserve the right to vary the same so far as consistent with the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination, with an ordinary scalebeam, of a calculating or price scale, and a coupler connecting the two, whereby the net value of the article weighed on the scale-beam is indicated on the price-scale, substantially as hereinbefore set forth.-

2. The combination, with a scale-beam and a price-scale, of a coupler-bar pivoted midway its ends, and links, one connecting the carrier end of the scale-beam to one end of the coupler, the other connecting the price-scale to the opposite end tially as described.

of the coupler, substanof the scale-beam and to base having a standard 3. The combination of the scale-beam, a price-scale, a coupler-bar fixedly pivoted relative to the scale-beam, links connecting the opposite ends of the coupler to the carrier end the price-scale, re-

spectively, and a movable platform or carriage supporting the price-scale, whereby the latter may be shifted to correspond with the price per pound of the article weighed on the scale-beam, substantially as and for the purpose specified.

4. The combination of the scalebeam, a

fixed to oneend thereof, a coupler pivoted to the standard and having one end connected to the carrier end of the scale-beam, a weighted link pivotally supported by the opposite end of the coupler, a carriage movable on the base, a price-scale carried thereby, and having one branch of its beammovable through the weighted link, as and for the purposes set forth.

5. The combination of an ordinary scalebeam, a base supporting a standard at one end, a coupler pivoted. to the standard midway its ends, a link connecting one end of the coupler to the carrier end of the scale-beam, and a price-scale supported on said base and adjustably connected with the free end of the coupler-bar, substantially as and for the purposes hereinbefore specified.

In testimony whereof I affix my signature in presence of two witnesses.

JULIUS E. PITRAT.
